Book review: Geology of gem deposits Book review: Geology of gem deposits
Geology of Gem Deposits is the most recent addition to the classic short course volumes published by the Mineralogical Association of Canada. Although not as comprehensive as the title might imply, this volume does contain overview papers devoted (in varying degrees) to the geology of diamond, beryl, corundum, chrysoberyl, tanzanite and tsarvorite, topaz, and jade deposits, as well as...

Geology and origin of epigenetic lode gold deposits, Tintina Gold Province, Alaska and Yukon Geology and origin of epigenetic lode gold deposits, Tintina Gold Province, Alaska and Yukon
More than 50 million ounces of lode gold resources have been defined in the previous 15 years throughout accreted terranes of interior Alaska and in adjacent continental margin rocks of Yukon. The major deposits in this so-called Tintina Gold Province formed around 105 to 90 million years ago in east-central Alaska and Yukon, and around 70 million years ago in southwestern Alaska, late...

Regional Fluid Flow and Basin Modeling in Northern Alaska Regional Fluid Flow and Basin Modeling in Northern Alaska
The foothills of the Brooks Range contain an enormous accumulation of zinc (Zn) in the form of zinc sulfide and barium (Ba) in the form of barite in Carboniferous shale, chert, and mudstone. Most of the resources and reserves of Zn occur in the Red Dog deposit and others in the Red Dog district; these resources and reserves surpass those of most deposits worldwide in terms of size and...

Nature of hydrothermal fluids at the shale-hosted Red Dog Zn-Pb-Ag deposits, Brooks Range, Alaska Nature of hydrothermal fluids at the shale-hosted Red Dog Zn-Pb-Ag deposits, Brooks Range, Alaska
The Red Dog Zn-Pb-Ag district in the western Brooks Range, northern Alaska, contains numerous shale-hosted Zn-Pb sulfide and barite deposits in organic-rich siliceous mudstone and shale, chert, and carbonate rocks of the Carboniferous Kuna Formation. The giant Red Dog shale-hosted deposits consist of a cluster of four orebodies (Main, Qanaiyaq, Aqqaluk, and Paalaaq) that lie within...

The late cretaceous Donlin Creek gold deposit, Southwestern Alaska: Controls on epizonal ore formation The late cretaceous Donlin Creek gold deposit, Southwestern Alaska: Controls on epizonal ore formation
The Donlin Creek gold deposit, southwestern Alaska, has an indicated and inferred resource of approximately 25 million ounces (Moz) Au at a cutoff grade of 1.5 g/t. The ca. 70 Ma deposit is hosted in the Late Cretaceous Kuskokwim flysch basin, which developed in the back part of the arc region of an active continental margin, on previously accreted oceanic terranes and continental...
